Centaurs are dynamically unstable due to strong interactions with the giant planets. The orbit of 2006 SX368 is unusually eccentric — near its perihelion, it comes under the influence of Uranus, while at the aphelion it travels slightly beyond the orbit of Neptune.[4]
It orbits the Sun at a distance of 11.9–32.0 AU once every 103 years and 2 months (37,683 days; semi-major axis of 22.0 AU). Its orbit has an eccentricity of 0.46 and an inclination of 36° with respect to the ecliptic.[1] The body's observation arc begins with its official discovery observation at Apache Point in September 2006.[3]
In 2010, thermal flux from 2006 SX368 in the far-infrared was measured by the Herschel Space Telescope. As a result, its equivalent size was estimated to lie within a range from 70 kilometres (43 mi) to 80 kilometres (50 mi).[4]
